Greenheck has announced that it will be building two new facilities on its Schofield, Wisconsin, campus, the Robert C. Greenheck Innovation Center and the Bernard A. Greenheck Education Center, to honor its founders.

The Vent-Free Fan Convectors are available in 10,000- and 24,000-Btu models and operate without vents or ductwork, making them suitable for room additions, basements, or sunrooms. 

Single-length 7-, 8-, 9-, and 10-foot-long models have been added to the ANSI/NSF 37-certified E-Zone and K-Zone (EZN and KZN Series) air curtains. 

RT-Series Inducers are designed to solve draft problems and are available with an optional Constant Operating Pressure Control (COP). 

The Cue Vent™ automates retrofitted standard HVAC registers by automatically changing the direction of the airflow with no motors, batteries, or electricity, using only a dynamic alloy wire that is temperature activated by the heater or air conditioner. 

Created specifically for spiral ducts, AP Spiralflex™ is a 100 percent fiber-free, elastomeric duct liner. 

If you’re reading this article in a building that has a forced-air HVAC system in it, you’re sitting inside the duct system right now.

Dairy farmer Hans Griesen was losing product and productivity due to freezing wintertime temperatures at his Madison, Wisconsin, milking parlor until he installed two air curtains.

Powered by a Vari-Green^® motor, Model SWD achieves the performance of the Model SWB belt-drive centrifugal utility fan, including higher operating efficiencies and higher-pressure capabilities. 

The webinar offers HVAC equipment engineers a basic review of fan engineering from an energy perspective.
